Literature search and article classification strategy for identifying potential areas of expansion for electronic health record data content. Articles returned by the search term “(electronic health record) OR (electronic medical record) OR (electronic health records) OR (electronic medical records)” were filtered by journal and the remaining articles matching the inclusion criteria were placed into general categories ①. A sample of 30 articles and their respective categories from this first pass through the literature were then evaluated for both the appropriateness of the article, the appropriateness of the categories, and the relevance of the articles to the categories (①). A second version of categories was then created and the process was repeated two more times (② and ③) using the previous set of categories from each pass yielding a final version of categories.
